Attention on T. kok-saghyz has revived due to allergic reactions to Hevea rubber used in medical devices, and to shortcomings in the supply of rubber from Hevea brasiliensis. The dandelion rubber used is cultivated, extracted and processed in Germany. The cultivation of dandelion also offers the opportunity to increase the diversity of cultivation on domestic fields. This blight may spread to the Hevea brasiliensis trees in Southeast Asia, which are genetically very similar to each other and to those of South America. This is used to achieve the following breeding objectives: Find more information about the research project and ecSeq's involvement in this information leaflet by the FNR, the central coordinating agency in the area of renewable resources in Germany: Receive updates about NGS articles and trainings.
